Rails - Jul 2006 - updating boolean field in model from check box value

hello

i am having a bit of trouble with updating the values of a boolean field 
in my database/model given the value returned by a check box

i am generating the check box as follows:

check_box("user", "enabled")

which produces

<input checked="checked" id="user_enabled"
name="user[enabled]"
type="checkbox" value="1" /><input
name="user[enabled]" type="hidden"
value="0" />

no problems there - it is reading the value out of the model/database 
and checking the box correctly

n.b. the database stores a 1 for true and 0 for false

however, if i uncheck the checkbox, for example, and update using this 
method in my controller:

def update
  @user = User.find(params[:id])
  if @user.update_attributes(params[:user])
    #success
  else
    #failed
  end
end

it doesn''t seem to commit the change

i have tried using the alternative check_box method specifying the 
checked and unchecked values as "true" and "false" but this
doesn''t work
either.

any ideas? thanks
